TUAV does not suffer from short operation time. Its main idea involves linking the UAV to the ground using a tether that provides both power supply and high-capacity backhaul. Consequently, the limited TUAV mobility is compensated by a longer operation time and higher backhauling capacity.
[1]} and [2]} introduced specific constraints to TUAVs such as limited tether length and safety considerations to avoid tangling the tether around surrounding buildings.
Also, they assumed that the tether serves both as power cable and wired backhaul link. This assumption implies complex and high cost tether and anchor designs. Alternatively, a simpler design can support power supply only, while relying on wireless backhauling through either radio or free-space optics [3]}.
